4+5

How many 5s are there in the following number series each of which is immediately followed by 4 but not immediately preceded by 6? 4 5 6 6 5 6 4 5 5 4 5 5 6 5 4 4 5 6 4 5 6 5 4 5 4 1) 1 2) 3 3) 4 4) 2 5)None of these

((4 +sqrt5)/(4-sqrt5)) +((4-sqrt5)/(4+sqrt5)) =?

How many 4's are there in the following series which is immediately followed by 5 but not immediately preceded by 3 ? 5 4 4 3 3 4 5 4 5 5 3 4 4 3 4 5 4 3 3 5 4 5 4 3 5 4 4 3 5 4 1) 0 2) 1 3) 2 4) 3 5) More than three

(4x+5)/(4x) = (4x)/(4x) + 5/(4x) = 1+5/(4x)

In the following sequence of instructions, 1 stands for Run, 2 stands for Stop, 3 stands for Go, 4 Stands for sit and 5 stands for wait. If the sequence is continued, which instruction will come next? 4,4,5, 4, 5, 3, 4, 5, 3, 1, 4, 5, 3, 1, 2, 4, 5, 4, 5, 4, 5, 3, 4, 5,3

Expand : (4t + 5)(4t-5)

The exponential form for (-2)^(4)xx(5/2)^(4) is 5^(4)

simplify :(4+sqrt(5))/(4-sqrt(5))+(4-sqrt(5))/(4+sqrt(5))

Simplify: (4+sqrt(5))/(4-sqrt(5))+(4-sqrt(5))/(4+sqrt(5))
